Gel permeation chromatography (GPC) and viscometry (V) methods have been combined for determination of long-chainbranching in bisphenol-A polycarbonate (PC) by means of a branching factor gv = M\*~/M\*, where M\*g and M\* are the apparent viscosity-average molecular weights calculated from GPC data

A new method for the determination of reliable molecular weight averages (MW) and polydispersity index (MWD) values for polydisperse polymers, directly analyzing their matrix-assisted laser/desorption ionization time-of-flight (MALDI-TOF) mass spectra, is reported. Our success is due to the concerte
Mathematical procedures are given for correlating the conformational parameters of the structural unit with the geometrical parameters of a polymer chain having sl symmetry.
A previously derived general equation, correlating the intrinsic viscosity of a polymer with -~'n, ~w and 2~,, is tested with experimental data. Its application for the calculation of average molecular weights is discussed. Good results have been obtained for the calculation of 2f/" z using experime
